A fluid end for a high-pressure pump including a unitary body with a plurality of horizontal passages each for receiving a reciprocating plunger at one of its ends and a pressure relief valve at the other of its ends. The body is provided with a corresponding number of vertical passages each of which intersect one of the horizontal passages and contains a suction valve at its bottom and a discharge valve at its top. A suction manifold is hingedly attached to the bottom of body to provide a flow of fluid into the body via the suction valves. A discharge passage intersects the vertical passages and receives fluid pressurized by the plungers via discharge valves and ports such from the fluid end.

What is claimed: 1. A fluid end comprising: a body having a horizontal passage, a vertical passage intersecting said horizontal passage, and a discharge passage intersecting the top of said vertical passage; said horizontal passage providing a counter bore to receive a reciprocating plunger and a pressure relief valve; said vertical passage providing a counter bore to receive a suction valve at the bottom of said vertical passage, and a discharge valve at the top of said vertical passage; a suction manifold adjustably secured to the bottom of said body and being in fluid communication with said vertical passage. 2. A body for a fluid end, comprising: a metal forging having: a horizontal passage which provides a counter bore to receive a reciprocating plunger at one end of said horizontal passage; a vertical passage intersecting said horizontal passage and having a suction valve seat deck at its bottom and a discharge valve seat deck at its top; a discharge passage intersecting the top of said vertical passage; a lifting eye in the top thereof to which a hoisting element can be attached; a pair of upright members joined by a cross piece, one of said upright members containing said vertical passage and the other of said upright members having a plurality of holes for mounting said body to the power end of a pump and said cross piece containing a horizontal passage; and means for providing affixment of pivot pins to the bottom of said upright member containing said vertical passage.
